BACKGROUND Tinea capitis and tinea faciei are dermatophyte infections of the scalp and glabrous skin of the face affecting mainly prepubertal children. During the past 30 years, a significant increase and a change in the pattern of infectious agents has been noted for tinea capitis. OBJECTIVES The aim of this study was to determine trends in the current epidemiological situation of tinea capi...

Dermatomycoses due to Trichophyton violaceum are described in Mediterranean Countries, North Africa and in the Horn of Africa where T. soudanense is present too, but it was rare until few years ago in Italy. Aim of the present study was to evaluate an Italian multicenter 9 year (2005-2013) experience concerning these re-emerging pathogens. Fifty three fungal strains were sent from clinical labo...

Occurrence of Chromobacterium violaceum in six protected drinking water springs in Uganda was investigated. C. violaceum showed a contrasting occurrence, which was independent of human impact as assessed by faecal pollution indicators. It was isolated from two springs (S1 and S2) that were located close to each other (3 km) but not in the rest. In S1 C. violaceum was continuously detected, in c...

A survey of Raktaja Krimis of Chhindwara was made during July, 1986 to June, 1987. Tinea infections were abundant followed by Tinea cruris, Tinea pedis, Tinear capitis, Tinea barbae, and Tinea unguinum. Tinea infections were common among the youth between 21 - 30 years. The percentage wise tinea infections were as follows : Trichophyton rubrum (64.5%), T. mentagrophytes (5.37%), T. violaceum (1...

BACKGROUND Tinea capitis affects mainly children. The frequency and causative organism vary from region to region. OBJECTIVES To provide epidemiological and mycological data on tinea capitis collected in urban and rural areas of the Dominican Republic. METHODS Samples were obtained from 118 patients with tinea capitis. Sixty-three of these were from 2 schools in urban areas of the Dominican...

BACKGROUND In the absence of a functional dermatophyte-specific polymerase chain reaction (PCR), current diagnosis of dermatophytoses, which constitute the commonest communicable diseases worldwide, relies on microscopy and culture. This combination of techniques is time-consuming and notoriously low in sensitivity. OBJECTIVES Recent dermatophyte gene sequence records were used to design a re...

Chromobacterium violaceum is a free-living microorganism, normally exposed to diverse environmental conditions; it has a versatile energy-generating metabolism. This bacterium is capable of exploiting a wide range of energy resources by using appropriate oxidases and reductases. This allows C. violaceum to live in both aerobic and anaerobic conditions. In aerobic conditions, C. violaceum is abl...

Out of 410 clinically diagnosed cases of superficial mycoses encountered during 1985 - 87, direct KOH mounts were positive in 250 (62.19%) cases and the cultures were positive in 123 (30.00%) cases. The organisms isolated included Trichophyton rubrum (36.58%). T. simii (32.52%), T.mentagrophytes (12.19%), C.tropicum (8.13%), Microsporum gypseum (6.50%), Epidermophyton floccossum (2.43%), T. vio...

BACKGROUND AND OBJECTIVES Cutaneous fungal infections are a major public health problem. The distribution of the dermatophytoses varies between countries and geographical areas. The aim of this study was to determine the incidence, epidemiology, etiology, and clinical course of the dermatophytoses caused by anthropophilic fungi in Cadiz, Spain, over the past 12 years. MATERIAL AND METHODS The...

Chromobacterium violaceum is a Gram-negative beta-proteobacterium that inhabits a variety of ecosystems in tropical and subtropical regions, including the water and banks of the Negro River in the Brazilian Amazon. This bacterium has been the subject of extensive study over the last three decades, due to its biotechnological properties, including the characteristic violacein pigment, which has ...
